/*
  A tool to stress-test poppler rendering and measure rendering times for
  very simplistic performance measuring.

  TODO:
   * make it work with cairo output as well
   * print more info about document like e.g. enumarate images,
     streams, compression, encryption, password-protection. Each should have
     a command-line arguments to turn it on/off
   * never over-write file given as -out argument (optionally, provide -force
     option to force writing the -out file). It's way too easy too lose results
     of a previous run.
